Largest number in [2, 3, .. n] which is co-prime with numbers in [2, 3, .. m]
Co-prime numbers are numbers that do not have any common divisor other than 1. We will be given two numbers n and m. We have to find the largest number in the range of 2 to n (both inclusive) which is co-prime with all the elements in the range of 2 to m (both inclusive). If none of the elements in the given range is co-prime with all the elements of the second range then we have to return or print -1. We will implement the approach, and code, and will discuss the time and space complexity of the program. ...
Read MoreP – smooth numbers in given ranges
P smooth numbers are the numbers that have the maximum prime number that can divide them is less than or equal to the given number P. Prime numbers are the numbers that are divisible by only 1 and that number. 1 is by default considered as the P - smooth number for any given value of P. In this problem, we will be given a value P and the range and we have to return the number of elements that are present in that range and are P-smooth. Input Given the value of P is 7 and the range ...
Read MoreHow do I show the schema of a table in a MySQL database?
To show the schema, we can use the DESC command. This gives the description about the table structure. The following is the syntax. DESCRIBE yourDatabasename.yourTableName; Let us implement the above syntax. mysql> DESCRIBE business.student; The following is the output. +-------+--------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------+--------------+------+-----+---------+-------+ | id | int(11) | YES | MUL | NULL | | | Name | varchar(100) | YES | MUL | NULL | | +-------+--------------+------+-----+---------+-------+ 2 rows in set (0.05 ...
Read MoreMaximum number of Strings with Common Prefix of length K
In this problem, we need to count the maximum string having common prefix of length K. We can take prefix of length K from all strings and count maximum number of similar prefix using the map data structure. Also, we can use the Trie data structure to solve the problem. Problem statement - We have given an strs[] array containing multiple strings. We need to count the maximum number of strings containing a common prefix of length K. Sample Example Input strs = {"tutorialspoint", "tut", "abcd", "tumn", "tutorial", "PQR", "ttus", "tuto"}; K = 3; Output ...
Read MoreMaximize value of Palindrome by rearranging characters of a Substring
In this problem, we need to find the maximum palindromic string by rearranging the characters of any substring of the given string. We will use bitmasking to solve the largest palindromic substring. If any substring has bitmasking 0, it contains all characters even a number of times. So, we can generate a palindromic string using the characters of that substring, and we need to find the maximum palindromic string among them. Problem statement - We have given a string containing the N numeric characters. We need to find the maximum palindromic string by rearranging the characters of any ...

TypeScript has been gaining popularity in the web development community for quite some time now, and for good reason. It is a powerful programming language that offers several benefits over traditional JavaScript. TypeScript is a strongly typed language that allows developers to catch errors earlier in the development process, making it easier to maintain and scale large codebases. In this article, we will explore why TypeScript is the best way to write front-end code. What is TypeScript? TypeScript is a superset of JavaScript that was developed by Microsoft in 2012. It is a statically typed language that provides optional ...
Read MoreWhy and How to Use TypeScript in your React App?
React has emerged as one of the most popular JavaScript libraries for building dynamic and interactive web applications in recent years. With its component-based architecture and virtual DOM, React offers developers a powerful and efficient way to create complex user interfaces. However, as projects grow in size and complexity, it becomes crucial to ensure code maintainability, catch potential bugs early, and improve collaboration among team members. This is where TypeScript, a statically typed superset of JavaScript, comes into play. In this tutorial, we will explore why and how to use TypeScript in your React app and how it can significantly ...
